Book Description
Currently adopted manual distress surveys involve a high degree of subjectivity, low production rates, and exposure to hazardous conditions. FDOT has acquired and validated a multi-functional survey vehicle (MPSV). However, when an automated crack distress survey operation is complete, FDOT must also use a reliable, accurate and speedy mechanism to analyze the distress information obtained from the survey. A number of automated and interactive crack measurement systems are available to assist pavement engineers to objectively evaluate pavement cracking from digital images of the pavement survey. Based on the findings of this research project the investigators found two such software packages which have the ability to function in conjunction with the imaging and inertial sub-systems of FDOT's MPSV and procedure repeatable and speedy distress evaluations. Of the two software that were studied in detail, namely, the Crackscope Program and the Workstation Program, the latter is more compatible with the MPSV.

Book Description
This report describes the development of a computer controlled direct-current potential-difference crack measuring system and its application to obtain crack growth rate data from centre-cracked-tension specimens. Details of the hardware and the software are included and the method and results fo the calibration for this type of specimen are given. Keywords: Direct current; Crack measurement; Computer applications; Crack propagation; Electric potential. (Australia).
